This math has probably been done before, and\ it's relatively useless as xp/dps is never constant, but I was curious so I took some time out to see what the numbers boiled down to and figured I'd share. At the very least bashing dps might be interesting to some.
The following are values for the amount of time required bashing per level (assuming constant essence per dps) compared to a level 80 baseline (without crit pendant), as well as comparative bashing dps values (in parens), so 250% of the baseline breaks down to 2.5x the bashing time (this DOES take dps changes due to crits into account), and a value of (1.25) in parens would mean you were doing 125% of the damage of someone without crit chance. There are also values for crit pendant levels 1/2/3, compared to the same level 80 no-critpendant baseline. In other words, if you hunt at the same xp/dps it will take you 5.3 times as long to bash level 98 to 99 as it will 80 to 81.
Feel free to call me out and make me look like an ass if I made any mistakes.
Snippet: Dragons with lvl 3 crit pendants only do 2.7x the bashing dps as level 80s without (yes I said only)
Snippet: At dragon, going from no crit pendant to crit pendant is a 30% dps increase while bashing (ikr)
Snippet: A level 3 crit pendant cuts your bashing time from 80-99 down by 19.4% compared to no pendant

Huh. Neat.

It could be me that's making a mistake somewhere, though. How are you calculating average crit modifier?
And wow a L3 pendant at dragon is only an 18% DPS increase? Isn't a L1 mace as Priest like a 25% DPS boost at any level?
My numbers were a slight bit off in the first post, but I'm still getting that dps increase from drag to drag with lvl 3 pendant is 27% increase and from 80 to lvl3drag is 2.6x
It's also very possible that this math is completely wrong and I've made a mistake, but I double-checked cause a few numbers had me questioning, and didn't see anything weird.
Your 27% looks about right to me. Crit rate is .405 at 99, .465 with L3 pendant. DPS is base_dps*2.39 without pendant, base_dps*3.02 with L3. Comes out to about a 26.5% increase.
Could also just do
Nothing wrong with your calculation, just suggesting cleaner ways to write the function because I had to write some stuff out to convince myself that yours was correct.
